ALFRED HEALD, OF PHILADELPHIA, PENNSYLVANIA;

WOVEN FABRIC.

SPECIFICATION forming part of Letters Patent No. 678,734, dated July 16, 1901.. I

Application filed October 24, 1900. Serial No. 34,149. (No specimens.)

To all whom it may concern/.-

Be it known that I, ALFRED HEALD, a citizen of the United States, residing in Philadelphia, Pennsylvania, haveinvented certain Improvements in Woven Fabrics, of which the following is a specification.

This invention constitutes a part of that forming the subject of my Letters Patent No. 661,640, dated November 13, 1900, the object of my present invention being to produce a fabric resembling an ordinary Brussels carpet fabric, both as regards the face and back, but which can he produced in anordinary loom without the use of pile-wire mechanism.

In the accompanying drawings, Figure 1 is an exaggerated section of my improved fabric, taken in the direction of the warp. Fig. 2is an exaggerated section of the fabric, taken in the direction of the weft; and Figs. 3 and 4 are views of another form of fabric embodying the invention.

The drawings,besides being exaggerated as to the size of the threads, show the fabric as of open texture in order that the course of the separate threads can be readily followed.

The actual fabric, while structurally similar to that'shown, will have the threads more closely bunched or beaten up.

The improved fabric consists of sets of patterning warp-threads alternating with pairs of binding warp-threads and pairs of heavy weft-threads, which may also, if desired, be used for patterning purposes, these heavy weft-threads alternating with pairs of binding weft-threads. Each set of patterning warp threads may comprise two, three, or more, these threads constituting, either alone or in conjunction with the heavy weftthreads, the surface threads of the fabric, whereby the pattern is produced. Each set of these warp-threads produces on the face of the fabric successive loops resembling the looped pile-threads of an ordinary Brussels carpet, the difference being that instead of being tied into a backing fabric and otherwise unsupported these loops are filled and supported by heavy weft-threads of the fabric. Either of the heavy weft-threads may serve as a pile-loop filling or supporting thread, and may also, in addition to performing this duty in certain parts of the fabric, appear upon the face of the fabric in other parts, so as to diversify the coloring of the pattern, the heavy weft-thread not so employed appearing upon the back of the fabric and the two weft-threads being tied together by the binding warpthreads, which also tie together the binding weft-threads, the latter serving to bind down and indent the pileforming warp threads between successive heavy weft-threads, so as to produce the desired pile-loop effect.

In the fabric shown in Figs. 1 and 2 of the drawings each set of patterning warp-threads comprises three threads 1, 2, and 3, these sets of warpthreads alternating with the binding Warp-threads 4 and 5 and the pairs of heavy weft-threads 6 and 7 alternating with the pairs of binding weft-threads 8 and 9, either of the patterning warp-threads of a set being carried to the face of the fabric, in accordance with the requirements of the pattern ,and the other warp-threads of the set being embedded between the upper and lower heavy weft-threads, as shown at A in Fig. 1, or all three of the patterning warpthreads of the set being embedded between the upper and lower heavy weft-threads, as shown at Bin Fig. 1, when either of said heavy weft-threads is carried to the surface of the fabric, in order to aid in the formation of the pattern.

That portion of the fabric which is lettered A resembles an ordinary Brussels carpet fabric, both as regards the face and back, the lower binder weft-thread 9 being by preference heavier and of a coarser character than the upper binder weft-thread 8, so as to in crease the weight and stiffness of the back of the fabric.

The fabric can be easily woven upon a loom such as is now employed for the weaving of ordinary two-ply ingrain carpet fabrics, since the insertion of the weft threads involves simply a repetition of a certain order of picking four shuttles, as in the ordinary ingrainloom. The jacquard mechanism, however, should be so constructed that any desired one of the harness-tails may be lifted on each pick of the loom. If desired, one of the binding warp-threads of each set may tie together the top binder weft-threads and the heavy back weft-threads,and the other binder warpthread of the set may simply be interwoven with the back binder weft-threads and the heavy back weft-threads, so as to form a back ply, as shown in Figs. 3 and 4.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A Woven fabric in whichsets of patterning warp-threads alternating with binding Warp-threads are interwoven with pairs of heavy weft-threads alternating with binding weft-threads, one or other of the patterning warp-threads of each set forming loops on the upper face of the fabric, and the remaining thread or threads of the set occupying an intermediate position between the upper and lower weft-threads, the upper heavy weftthreads distending the pile-loops on the face of the fabric and the lower heavy weft-threads appearing at the back of the fabric, the upper binding weft-threads tying down and indenting the pile loops between successive heavy weft-threads on the face of the fabric and the binding warp-threads aiding in the formation of the back of the fabric and tying said upper binding weft-threads to said back, substantially as specified.

2. A woven fabric in which sets of patterning warp-threads alternating with binding warp-threads are interwoven with pairs of heavy weft-threads alternating with pairs of binding weft-threads, one or other of the patterning warp-threads of each set forming loops on the upper face of the fabric and the remaining thread or threads of the set occupyin g an intermediate position between the upper and lower weft-threads in some parts of the fabric, and all of the patterning warpthreads being embedded between the upper and lower weft-threads, in other portions of the fabric, the upper heavy weft-threads either distending the pile-loops of the upper face of the fabric in some portions of the same, or overlying the patterning warp-threads in other portions of the fabric, the lower heavy weft-threads appearing on the back of the fabric, the binding weft-threads tying down and indenting the pile forming surface threads between successive upper heavy weftthreads, and the binding warp-threads aiding in the formation of the back of the fabric and tying said upper binding weft-threads to said back, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

ALFRED IIEALD.
